Abstract: Xiangdong tungsten deposit is located at the contact zone of Yangtze Plate and Huaxia Plate,it is distributed in the intersection part of Dengfushan-Zhuguangshan NW-trending tectonic magmatic zone and Lingxian-Linwu NE-trending tectonic magmatic zone,the genesis of the deposit is quartz vein type tungsten deposit.The mining activities of the mining area has been lasted for more than 60 years since the mine is put into operation in the 1950s.The tungsten resources already explored in the mining area is close to depletion,the mine is gradually becoming the resource crisis mine.It is of great significance to conduct the prospecting work of the depth of the mining area and its adjacent area,to expand the resource reserve and extend the service live of the mine.Based on the geological prospecting results newly obtained in the minging area,the regional metallogenic geological background,geological characteristics of the mining area and tungsten deposit are discussed,and the deep prospecting prediction of tungsten deposit of the mining area is done.The study results show that:①the metallogenic material and space are provided by the large fault (it is mainly composed by EW-trending Laoshanao fault (F1) and NE-trending Jinzhulong fault (F2)) formed by medium mica granites magma and tectonic activity in Early Yanshanian,the ore veins after mineralization are broken by the tectonic activity in Late Yanshanian;②the main tectonic activities such as extrusion activity in Caledonian and Indo-Chinese Epoch,extending activity in Early Yanshanian,extrusion activity in Late Yanshanian are developed in the mining area;③according to the metallogenic geological characteristics of the mining area,the deep prospecting results indicated that the prospecting potential of the deep fracture developed zone of the lower of Laoshanao fault (F1),east and deep of SS2 and SS3 ore veins,depth of F8 fault are huge,it is necessary to conduct further prospecting and exploration work in theses areas.
